.
When using two Rolling Inductors, Two IR sensors can be used at the same time.
.
Workpieces should be the same size and material when using two Rolling Inductors on one power source.
NOTICE −TC5 and TC6 connect to the Rolling Inductor internal thermocouple which monitors internal Rolling Inductor core temperatures.
Measure workpiece temperature with temperature crayons, infrared sensors, or contact thermocouples placed within two inches of the Rolling Induc-
tor.
Set Trvl Detect to On if using travel detection.
.
Must be set to Off if not using Trvl Detect, or unit will not activate heat output.
Travel detection is recommended for all Rolling Inductor applications. It assists in maintaining an even heat input to the part and regulates output
power based on travel speed in Temp mode.
Set Trvl Speed units as needed.
